If anyone is curious I was able to get it working by running these commands as root (kernel 3.15+)
 
# cd /usr/lib/modules/3.15.3-1-ARCH/kernel/drivers/bluetooth/
# cp ath3k.ko.gz ath3k.ko.gz.orig
# cp btusb.ko.gz btusb.ko.gz.orig
# gunzip ath3k.ko.gz
# gunzip btusb.ko.gz
# sed -e 's/\xf3\x0c\x02\x30/\xf3\x0c\x02\xe0/g' ath3k.ko > at.ko
# sed -e 's/\xf3\x0c\x02\x30/\xf3\x0c\x02\xe0/g' btusb.ko > bt.ko
# mv at.ko ath3k.ko
# mv bt.ko btusb.ko
# gzip ath3k.ko
# gzip btusb.ko
# rmmod ath3k
# rmmod btusb
# modprobe btusb
# modprobe ath3k

I just stumbled across this, and it works. 
 
But I have to ask... How did you EVER find the one byte in the kernel modules that needed to be changed?
